Electronic thermometers for rectal body temperature measurement showed lower accuracy compared to mercury thermometers. Regular calibration of electronic devices is essential for reliable fever detection in adult patients.

Area of Science:

  • Medical Devices
  • Clinical Thermometry
  • Patient Monitoring

Background:

  • Accurate body temperature measurement is crucial for diagnosing and managing febrile illnesses.
  • Traditional mercury thermometers have been widely used, but electronic alternatives offer potential advantages in speed and safety.
  • The reliability of electronic thermometers in clinical settings requires rigorous evaluation.

Purpose of the Study:

  • To compare the accuracy of electronic (Ivac) thermometers with mercury thermometers for rectal body temperature measurement.
  • To assess the impact of calibration on the accuracy of electronic thermometers.
  • To provide recommendations for the clinical use of electronic rectal thermometers.

Main Methods:

  • A comparative study involving 157 adult patients on a medical ward.

  • Rectal body temperature was measured simultaneously using both electronic (Ivac) and mercury thermometers.
  • Data analysis focused on the agreement and discrepancies between the two measurement methods.

    • Main Results:

    • Electronic (Ivac) thermometers demonstrated lower accuracy, identifying 3.6 times more patients as febrile compared to mercury thermometers.
    • Following thermometer calibration, the discrepancy was reduced, with electronic thermometers identifying 1.6 times more febrile patients.
    • A significant difference in accuracy was observed between the two thermometer types, even after calibration.

    Conclusions:

    • Regular calibration of Ivac electronic thermometers is necessary to ensure accurate rectal body temperature readings.
    • The findings highlight potential inaccuracies in non-calibrated electronic thermometers, impacting patient diagnosis.
    • Further research into optimal calibration protocols for electronic thermometers in clinical practice is warranted.
